Mary Sweet has just opened a candy shop. The store is open from 10 a.m. to 8 p.m. each day, which means that Mary must work a minimum of 10 hours a day for seven days a week. In addition to sales, she also must spend time on purchasing, paying bills, and cleaning up. Mary quickly decides that she needs to hire help. Her first hire is a person to operate the cash register for five days of the week. This person also will be responsible for closing the shop on those days so Mary can spend the evenings with her family. While Mary was operating the store by herself, she did not have to worry about control issues. Now that she is hiring another person, she must consider mechanisms to control the new employee.

Describe some control problems that might arise and some mechanisms that Mary could use to help control those problems.
